When you update something in your domain’s DNS settings — like changing nameservers, adding MX records for email, or pointing your domain to a new hosting provider — those changes don’t become visible everywhere on the internet instantly. Instead, they go through a process called DNS propagation.
Propagation is the time it takes for your new DNS information to be shared and updated across DNS servers around the world. Since each server caches DNS data for a certain period, it may take time before every server reflects the latest changes.
On average, DNS propagation takes anywhere from a few minutes to 24 hours, depending on the type of record you updated. In some cases, it may take up to 72 hours for all servers worldwide to catch up.
-
A and NS records (which map your domain to an IP address or set your nameservers) usually update more quickly.
-
Other records, like MX (for email), may take longer to fully update.
How to Check DNS Propagation
You don’t need to guess whether your changes are live. You can use free online tools like DNS Checker to see the current status of your domain’s records.
Here’s what the results usually mean:
-
All ❌ marks – No propagation yet. If it has already been more than 24 hours, this may signal an issue with your settings.
-
A mix of ❌ and ✅ – Your domain is in the middle of propagation. Some servers recognize the new settings, while others are still catching up.
-
All ✅ marks – Propagation is complete, and your domain should be working correctly everywhere.
If you still face issues after propagation is done, try clearing your device’s DNS cache and rechecking. You can also read our guide on [how to troubleshoot common DNS issues].
